Martel Electronics OEM1B - Manual

PRODUCT DESCRIPTION
The OEM 1B uses the latest miniaturisation techniques to produce a very compact 3 ½ digit LCD voltmeter. It is
designed to be a drop-in component in most medium and high volume applications, ranging from personal
instrumentation and integral sensor indicators to measurement probes. The meter features 8mm digit height, 3
decimal points, auto-polarity, auto-zero, 200mV full scale reading and a very low current consumption.
Connection to the module is via two dual in line rows of pins.

SAFETY
To comply with the Low Voltage Directive (LVD 93/68/EEC), input voltages to the module’s pins must not exceed
60Vdc. The user must ensure that the incorporation of the panel meter into the user’s equipment conforms to the
relevant sections of BS EN 61010 (Safety Requirements for Electrical Equipment for Measuring, Control and
Laboratory Use).

* To ensure maximum accuracy, re-calibrate periodically.
** Operation of the meter beyond the maximum supply voltage rating may cause permanent damage to the meter.
Unless otherwise noted, specifications apply at T =25°C, V =5Vd.c. (f =48kHz) and are tested with the module configured for floating input
mode.
